Recreational trail traffic counts and trail proximity as a driver of ungulate landscape utilization

Ecosphere, Volume 16, Issue 6, June 2025.
Abstract With continual growth in recreational trail use, it is becoming increasingly complicated to balance demands for outdoor recreation opportunities with wildlife conservation. To better understand how mule deer (Odocoileus hemionus) and Rocky Mountain elk (Cervus canadensis) respond to trail‐based recreation, we deployed remote cameras in a ...

Interspecific carnivore competition and ungulate predation correlate with predator species richness

Ecology, Volume 106, Issue 6, June 2025.
Abstract Competition for resources underlies the development of ecological community structure and function. Niche compression occurs when species reduce resource use due to competition, and niche complementarity posits resource competition should occur sequentially among habitat, time, and food.

Telemetry Studies of Mountain Ungulates in the Greater Yellowstone Area: A Progress Report [PDF]

, 2013
We report on the progress that has been made on initiating long-term telemetry studies of mountain goats (Oreamnos americanus) and bighorn sheep (Ovis Canadensis) in the GYA to better understand spatial ecology, demography, potential competition, and ...

Pneumonia in bighorn sheep: Risk and resilience

The Journal of Wildlife Management, 2017
ABSTRACTInfectious disease contributed to historical declines and extirpations of bighorn sheep (Ovis canadensis) in North America and continues to impede population restoration and management. Reports of pneumonia outbreaks in free‐ranging bighorn sheep following contact with domestic sheep have been validated by the results of 13 captive commingling ...

Wildlife students as community scientists provide statewide detection data to help non‐invasively monitor Oklahoma bobcats

Wildlife Society Bulletin, Volume 49, Issue 2, June 2025.
We recruited students from Oklahoma's universities to non‐invasively collect bobcat presence data using hair‐snare devices. Bobcat probability of use models showed imprecise effects of land cover types but county‐level harvest rates were better estimators, though are liable to adjust based on non‐ecological factors. Our study suggests wildlife students

Techniques for capturing bighorn sheep lambs

Wildlife Society Bulletin, 2013
ABSTRACTLow lamb recruitment is a major challenge facing managers attempting to mitigate the decline of bighorn sheep (Ovis canadensis), and investigations into the underlying mechanisms are limited because of the inability to readily capture and monitor bighorn sheep lambs.

It's time to go—Drivers and plasticity of migration phenology in a short‐distance migratory ungulate

Journal of Animal Ecology, Volume 94, Issue 6, Page 1204-1220, June 2025.
In thishis study, we reveal how vegetation phenology and snow dynamics drive the timing of migration in a short‐distance migratory ungulate inhabiting the Alps. Differences appeared between sexes, suggesting that female ibex could be constrained in their migration timing because of parturition, questioning the consequences of rapid climate change in ...

Population Trends of Bighorn Sheep and Mountain Goats in the Greater Yellowstone Area [PDF]

, 2016
Bighorn sheep (Ovis canadensis) and mountain goats (Oreamnos americanus) are important components of the large mammal community in the Greater Yellowstone Area (GYA) and are of considerable public interest.

Source population and time spent in captivity affect survival and reproduction of long‐distance translocated northern bobwhites

Animal Conservation, Volume 28, Issue 3, Page 365-379, June 2025.
Long‐distance translocations of northern bobwhites are increasingly used to access source populations with sufficient densities for translocation. This study compared the survival and productivity of bobwhites translocated from the South Texas Plains and the Floridian Coastal Plain to the Floridian Coastal Plain, revealing higher survival and fecundity
